I am trying to determine which modifier is appropriate to report to Medicare for the 92199 procedure we are billing for a Fibroscan. We are having our patients sign the ABN b/c we are not certain Medicare will cover it, but I am not sure which modifier I should use? GX, GY or GZ. Im leaning towards GY but any thoughts are much appreciated!
